Summary: The unstable cycling performance of Mo2CTx MXene as a Li-ion battery anode is attributed to partial oxidation and structural degradation. To address this issue, a laser-induced Mo2CTx/Mo2C hybrid anode was developed, which showed improved redox kinetics, prevented structural degradation, enhanced conductivity, and improved cycling stability. The laser-induced synthesis approach demonstrates the potential of MXene-based hybrid materials for high-performance energy storage applications.

Summary: Potassium-ion batteries (KIBs) are considered as an alternative to lithium-ion batteries due to the abundance and low cost of potassium. However, the volume change during the insertion and extraction of large-sized potassium ions leads to structural collapse and irreversible charging/discharging process. In this study, a nanoengineered material, MoSe2/NP-HCNS, was synthesized through thermal annealing and heteroatom doping strategies. This material has a cleverly designed hierarchical nanostructure that can accommodate volume change, enhance electrolyte penetration, and prevent aggregation of MoSe2 nanosheets. The MoSe2/NP-HCNS anode exhibits high reversible capacity and long cycling life, making it a promising anode material for KIBs.

Summary: This article presents a flexible etch-assisted sulfidation strategy for the anode material in potassium-ion batteries. The strategy involves constructing a multicore-shell nanocapsule structure and encapsulating mesoporous FeS2 nanoparticles in a hollow carbon shell with adjustable interior space. The resulting material, MCS-FeS2@C-20, exhibits optimized inner space, large reversible capacity, good rate capability, and excellent cycling stability, making it a promising anode material for PIBs. Notably, potassium-ion full cells using MCS-FeS2@C-20 also show improved potassium storage performance.
